Having thus described my invention, what I claim as new is: 1. Incombination with a tractor having a frame with a depending front bolsterstructure including steering operating mechanism, a bolster assemblycomprising a pair of cross bars bolted to the front of the frame, avertical plate secured to the centers of the cross bars and extendingtherebelow, a bolster 10 bar secured to the plate and extending belowthe plate, an axle having its center bolted to the lower extremity ofthe bolster bar, steering knuckles on the ends of the axle, wheels 7 onthe steering knuckles, arms extending from the steering knuckles, aconnecting rod between the arms, an arm operatively connected with thesteering mechanism and pivotally connected with the center of theconnecting rod. V 2. In combination with a tractor having a frame with adepending front bolster structure including steering operatingmechanism, a bolster assembly comprising a pair of cross bars bolted tothe front of the frame, a ver- 5 tical plate. secured to the centers ofthe cross bars and extending therebelow, a bolster bar secured to theplate and extending below the plate, an axle having itscenter bolted tothe lower extremity of the bolster bar, steering knuckles on the ends ofthe axle, wheels on the steering knuckles, arms extending from thesteering knuckles, a connecting rod between the arms, an arm operativelyconnected with the steering mechanism and pivotally connected with thecenter of the connecting rod, said plate having a side flange along oneside edge of the bolster bar.

3. In combination with a tractor having a frame with a depending frontbolster structure including steering operating mechanism, a bolsterassembly comprising a pair of cross bars bolted to the front of theframe, a ver-' tical plate secured to the centers of the cross bars andextending therebelow, abolster bar secured to the plate and extendingbelow the plate, an axle having its center bolted to the lower extremityof the bolster bar, steering knuckles on the ends of the axle, wheels onthe steering knuckles, arms extending from the steering knuckles, aconnecting rod between the arms, an arm operatively connected with thesteering mechanism and pivotally connected with the center of theconnecting rod, a V-shaped brace having its ends fixed to the ends ofthe axle and extending rearwardly, a second V-shaped brace having itsends fixed to the frame and inclining downwardly and rearwardly, meanspivotally connecting the apexes of the V-shaped brace. In testimonywhereof I aflix my signature.
